What are the interesting theories about faster than light travel?3 answersFaster-than-light (FTL) travel has been a topic of interest in both science fiction and scientific research. Three principal FTL concepts have been explored: tachyons, which are hypothetical FTL particles consistent with the special theory of relativity; wormholes, which involve using general relativity to create shortcuts through spacetime; and warp drives, which modify spacetime to bypass the speed of light limit. However, there are challenges and limitations associated with these concepts. Some physicists argue that relying on general relativity for FTL travel is not desirable due to its chaotic internal logic and reversed causality. Another approach is electromagnetic propulsion, such as the EM drive, which is considered feasible for FTL travel. Additionally, there are theories that connect FTL travel with the Riemann Hypothesis and topological propulsion.
How can quantum theory be used to explain the behavior of the universe?3 answersQuantum theory can be used to explain the behavior of the universe by providing a probabilistic framework for understanding events that occur just once, such as the creation of the universe and the actions of matter within it. Additionally, the non-local property of fractal curves, described by fractal calculus, can naturally lead to the emergence of quantum phenomena, including Planck's energy quantum formula and Heisenberg's Principle of Uncertainty. The pragmatist interpretation of quantum theory suggests that quantum states serve as a source of advice for physically situated agents, helping to explain regularities such as single particle interference phenomena, the stability of matter, and interference of Bose-Einstein condensates. Furthermore, the quantum density of the universe, which describes the concentration of quantons in quantized space-time, can be mathematically described using quantum theory, providing insights into the condition of our curved and heterogeneous universe. Quantum theory can also be applied to the universe as a whole, with concepts such as the universality of quantum theory and the emergence of classical behaviors through decoherence playing a crucial role in understanding quantum cosmology.

Amyloid and Tau hypotheses
5 answers
The amyloid hypothesis suggests that the accumulation of β-amyloid peptide (Aβ) in the brain is a key factor in Alzheimer's disease (AD) development. On the other hand, the tau hypothesis focuses on the role of tau protein phosphorylation (pTau) in AD pathogenesis, with increased pTau levels contributing to synaptotoxicity. Recent research has explored the relationship between Aβ and tau, indicating a potential causal link between the two pathologies. Studies have shown that while Aβ may initiate the aggregation of tau, genetic factors and neuroinflammation could also play significant roles in AD progression. Additionally, evidence suggests that pTau phosphorylation near microtubule domains may actually act as a neuroprotective mechanism, challenging the traditional view of tau's role in neurodegeneration.
